Definitions

  • the present invention relates to an installation or plant for manufacturing half warm mix asphalts, as well as to a method for operating such an installation or plant.
  • a mix asphalt is generally a combination of asphalt and stone mineral aggregates in exact proportions. The relative proportions of these minerals determine the physical properties of the mix asphalt in question and, possibly, the performance thereof as a finished mix for a determined use.
  • the mix asphalt must be durable, i.e., it must be resistant to actions such as the detachment of the asphalt film from the aggregate due to the effects of the water, of the abrasion from traffic, etc. Likewise, it must be resistant to traffic stresses through its stability. Furthermore, a mix asphalt must be impermeable so that its components are not under the direct action of atmospheric agents, and at the same time it must be possible to work on it to allow its easy placement and compaction on the ground. Each of these are desirable properties of mix asphalts.
  • the mentioned mix asphalts can be made in plants by means of suitable equipment for performing this task. According to the properties of these mix asphalts, as well as their layer thicknesses, it is considered that they provide structural capacity to the pavement on which they are arranged.
  • the production and application of mix asphalts under hot conditions typically requires the materials to be heated between 135oC and 180oC. This temperature is partly dictated by the viscosity of the asphalt binder and is necessary for assuring a homogeneous and complete coating of the aggregates by the asphalt.
  • the present invention is aimed at solving the aforementioned drawbacks.
  • DE102005020836 A1 describes a mobile assembly prepares asphalt aggregates on-site for highway construction, comprising a drier with a drying drum to both dry and heat minerals, and a mixer tower to mix the dried minerals with bitumen and conversion to asphalt.
  • the mixer tower incorporates a mixer mechanism.
  • the mixer tower unit is divided into linked lower and upper sections. According to the mixing tower unit is thus divided into two separate transported on trailers modules, namely a stationary module, which comprises mixing tower base, and a self-righting module, which comprises mixing tower shell.
  • the automatic erection can in this case in particular by a rotary movement, effected by a pivoting movement.
  • the first and second trailer advantageously previously are coupled together.
  • the present invention relates to a plant for manufacturing half warm mix asphalts in a controlled manner, such that main advantages of the plant of the invention with respect to known plants are the following:
  • the plant for manufacturing half warm mix asphalts comprises all the features of claim 1. According to a second aspect, the invention relates to a method for operating such a plant according to claim 9. Other features and advantages of the present invention will be inferred from the following detailed description of an illustrative embodiment of its object in relation to the attached figures.
  • the present invention develops, in a first aspect, a plant 1 for manufacturing half warm mix asphalts in a controlled manner, which comprises:
  • the plant 1 for manufacturing half warm mix asphalts is a completely moveable plant which can be assembled in four moveable platforms 10, 20, 30 and 40.
  • the plant 1 of the invention in turn comprises at least one silo 50 for storing and unloading cement, this silo preferably being horizontally arranged by means of a platform with extendable legs.
  • the silo 60 for storing and unloading filler is also preferably horizontally arranged by means of another platform with legs which are extendable to the floor.
  • the fuel tank 70 of the plant 1 is preferably arranged on a horizontal platform, the tank 80 for storing and unloading emulsion material being located on another platform to the floor.
  • the versatility of the plant 1 of the invention makes it possible to, with one and the same type of plant 1, obtain different end products, in addition to the half warm mix asphalts or warm agglomerates, such as: soil-cement, gravel-cement, gravel-emulsion, cold agglomerate, concrete, agglomerate recycling or asphalt recycling, etc.
  • any of the silos for cement, 50, or for filler, 60, as shown in Figure 7 (for the particular case of a cement silo 50) comprises: a filter 51, a loading worm screw 52 and an unloading worm screw 53.
  • the filter 41 of the third moveable platform 40 allows collecting powders in the asphalt industry. This filter 41 allows reducing powders to the lowest possible level according to the current standard.
  • the separation of the powder and of the gas occurs in the bags of the filter 41.
  • the filler accumulates as a coating in the outer surface of the mentioned bags, the washing of which is obtained by means of a rotating mechanism creating a reverse air flow. The washing is done section by section, sending an atmospheric air flow through the bag.
  • the powder which will cover the bags collapses and falls into a collecting hopper, being sent to the plant 1 through a flap valve.
  • the cylinder of the drying drum 33 works according to the counterflow method, directing the aggregates towards the flame.
  • the drying drum 33 is loaded with a feeding belt or shuttle belt 32, the cylinder of the drying drum 33 being inclined towards the unloading, and being actuated by friction.
  • the vanes in the area in which the flame is located orient the aggregates around the flame but do not interrupt the combustion process.
  • the invention relates to a method for operating a plant 1 as has been defined above, this method comprising the following steps:
